Answer:
h(x) = 44
Step-by-step explanation:
h(x) = x² - 5, h(-7) means x = -7
h(x) = (-7)² - 5
h(x) = 49 - 5
h(x) = 44
 
        
                    
             
        
        
        
F (x) = x^3 - 27 / x^2 + 2x - 15
 
        
             
        
        
        
a+y≤1000 and 25a+12.50y>15000 is the system of inequalities that could be used to solve the problem.
Step-by-step explanation:
Given, 
Price of one adult ticket = a = $25
Price of one youth ticket = y = $12.50 
Maximum people that can be hold by theater = 1000 
Therefore; 
The maximum number of people can be 1000 or less than that.

As they want to revenue to be more than 15,000 therefore, 

a+y≤1000 and 25a+12.50y>15000 is the system of inequalities that could be used to solve the problem.

Answer:
z = 106°
As a straight line has total 180°
Find the top inside angle:
t + 142° = 180°
t = 180° - 142°
t = 38°
Two opposite angles sum up to exterior angle.
<u>Now find z:</u>
68° + 38°
106°
